To all'wzomt may conce/rn.-

Be it' known that I, Ronnnro- T. E.` Oli-- russa, a; citizen oi"IGermany', and airesident of the city ofibntigua, Guatemala', GentralfAmerica, have invented .a new and Improved Sugar Mill orv Gane Crusher,oi which the' -followingxis a fulhclear., and exact `description. v o

rlhis invention relates to sugar mill mar chinery and particularly to amimproved cane crushing strl'lcture -andrllas for an' obi ject to providean improved' construction wherein the pressure'oir the crrushing' rollsisautomat'ically maintained'v at a given@ tension:v`

It will henoted-ironrFigure 1 that the rollers arev yarranged in a triangle and that the cane is fed -in through the chute 21so that it may pass between the rollers and 16. From these rollers thecane passes through the rollers 16 and 17 and' finally out through thedischarge chute 22.

In order that the crushed or partially crushed cane may freely, pass therollers 15 and 17, a guide or conveying block 23 is provided which maybea casting and which is provided with upstanding guiding flanges 24 and25 adapted to straddle the roller 16. A plurality of notches 26 arearranged in one edge whereby a toothed structure is pre sented, saidnitches being provided so that the cane may Ibe properly guided to theroller-` 17 while the From Figures 3 and'4, it will be noted that theblock 23 is provided with a) pair of depending bearinglugs 27 forreceiving the respectivesupporting bars 28 and 29,

each of whichhas an adjustable bearing pin 30 at the bottom resting onthe respective bearing blocks 31. The block 23 also is provided withapair of depending arc-shaped arms 32, thelower ends ofwhich accommodatea friction' plate 33 adapted to .bear

Vpress more or klessv firmlyV against the roller 15, which pressure isaugmented somewhat by the downward pressure of the cane as it passesover the Y guiding block 23. Also, meanshave beenprovided for holdingthe block 23 in'place and the friction `pl-ate34 properly .pressingagainstthe roller.

This means consists v"of a pair of links 35, there being onelinkarranged at each end oftheblock 23. Each of these links is provided withan elongated opening 36 accommodating the Vrespective Vjournal pins 37ex- V tending from the ends of the block 23.` The 38 and' arranged tostraddle part of the links l35' while `substantially onthe diametricallyend of the link opposite that'carrying the Y slot 36 Vis provided withfa comparatively large aperture designed toV accommodate the disk 38which is provided with an eccen trically positioned aperture throughwhich the shaft 2O extends. A pair of small guiding plates 39 is rigidlysecuredto the disk oppositer side isl arranged a U-shapedmember 40having the legs riveted or otherwise secured to the disk 38. -TheU-shaped member V40 carries a set'screw 41 which is adapted to bescrewed down and pinch the linksV 35 so as to lock the disk 38 and thelinks 35 together. .In case of wearing ofthe rolljuice may drop .downv`into the pan 2.

er 15 or of the plates 33 and 34, screw41 may Vbe loosened andv theeccentrically mounted disk38 rotated somewhat until the parts aretightand then the set screw 41 tightened. In this way, the position of theblock 23 and associated parts may be readily adjusted totake care ofwear or to provide any desired tightness or looseness of connection. f

When the Crusher is in'use, cane is fed into the chute 21 and as itmovesbetween the rollers 15 and 16, these rollers mayseparate somewhatif the supply is great, said separation causing the levers' 7 to swingbutby reason of the arrangement of the weight 14 and associatedparts,.a. continued even pressure will be supplied. As the crushedorpartially crushed cane passes the roller 17 isi'rornthe.l roller 16.This'will cause a,` preliminary; crushing vand .then .a final crushing.f

yrollers 15 .and 16,V it will engage thevblock In order to adjustthe.rollers in respect. i

. to the levers 7, any desired number of bolts 42'extend throughsuitable apertures in thev y -eccentrics 6 and through vthe respectivelevers 7. By'removing these bolts and shifting the eccentrics. 6 andthen-re-applying the bolts different adjustments may be se# cured.lleretofore it has been difficult to properly guide the cane from theroller 15 to the roller 17 and'quite` often Vthe lmass of crushed orpartiallycrushed cane would accumulate betweenthese two rollers andprevent-aV proper functioning of the apparatus.

'Byproviding the contact plate 34, a substantial shaving action of*roller 15 will Ibe provided and Uhe'matter thus shaved fromV the rollerA15vwill freely pass over the block 23 to the roller 17 without cloggingany part ofthe mechanism and the finally crushed cane or pulp will bedischarged out vllthe chute 22.

In Figures7 and 8 a slightly modified construction is shown inVrespect-to the guiding block 23. In this form of the invention'` itwill Vbe observed thatgthe block 23y is provided merely with a shaving0r wearing plate 34f'and the plate 33-'is-eliminated. It

will also be noted that in thisform of the invention a rsingle integrallug 43 extends `from the lower'part vof the block 23 and projectsthrough a bracing bar 44, whichl bar is connected in any desired mannerwith the supporting bars 28 and 29. A nut 45 is screwed Vonto the lug 43so as to clamp the parts firmly together while allowing the Vbars 28 and29 to rock freely'in Vthe respective supports 31.

What I claim is 1. A crusher for cane mills, comprising three crushingrollers arranged in a triangle, a pair of levers connected With each ofthe two lower rollers, means including a flexible member and Weightacting thereon co-acting with said levers and rollers for automaticallycausing the levers to swing the lower rollers toward and from eachother, and means for guiding vcane to said rollers.

2. In a cane crushing apparatus, a plurality of crushing rollers andguiding means for guiding cane from one roller to the other, saidguiding means including a. guiding block having a plurality of notches,and a pair of depending arms, a, pair of roller engaging platesconnected to said block and to the arms thereof, means for holding saidplates in frictional engagement With one of said rollers, and means forsupporting said block While allowing a limited swinging movementthereof.

3. In a cane crushing apparatus, a plurality of crushing rollers andguiding means for guiding the cane from one roller to the other, saidguiding means including a guiding block frictionally engaging one o-fthe rollers, means for supporting the block, and means for holding theblock against one of the rollers, said last mentioned means including apair of links pivotally connected With the block, an eccentricallymounted disk rotatably mounted in each of said links, and meansforlocking the disks in different positions in respect to the links. Y

4. A cane crushing apparatus of the character described, comprising afixed crushing roller, a pair of movable crushing rollers co-acting withthe fixed crushing roller, each of the movable crushing rollers having ashaft extending therefrom, eccentric members mounted on said shafts,abearing block for each of said eccentric inembers, a pair of levers foreach of said movable rollers, means forclainping the eccentrics to therespective levers so that when the levers are lswung back and forth theeccentrics will be rotated and the movable rollers Will be movedsubstantially toward and from each other, a pulley carried by each ofsaid levers near the upper end, a chain secured to one of the levers andreeve over said pulleys, and a Weight actv ing on said chain for pullingthe same so as to give the levers a tendency to move towards each otherand consequently swing said movable rollers toward each other.
